摘要
中国石油兰州石化分公司460 kt/a乙烯装置为实现节能降耗,对蒸汽凝液工艺流程进行了2次优化改造,合理回收了蒸汽凝液的余热,用于加热脱盐水,降低了乙烯装置低压蒸汽用量,优化了操作条件,实现了装置节能降耗,使装置的低压蒸汽用量减少了16.5 t/h左右,降低装置综合能耗约18 kgEo/t。
PetroChina Lanzhou Petrochemical Company 460 kt/a ethylene plant to realize saving en-ergy and reducing consumption, with steam condensate process conducted two optimization transforma-tion, reasonable recycling the waste heat, steam condensate is used to heat the desalted water, decrease the dosage of low pressure steam in ethylene plant, optimized operating conditions, realized energy saving device, the device of low pressure steam consumption reduced 16. 5/h, about 18 kgEo/t cut down com-prehensive energy consumption of unit.
